typewriter key may be removed.

vide the tool with a panying drawing,

One object of the invention is to providev of which the collar of a typewriter key may be readily removed without` damage to the key or coll ar.

Another object of the invention 1s to permit jaws forming (part of the tool to .be readily adjusted an moved into firm gripping engagement with the collar of the typewriter key.

Another object of the invention is to so mount the jaws that they may be. firmly held in place when in use but permitted to be readily removed and others substituted.

Another object of the invention is to prohandle which may be formed from a length of metaltubingand firmly secured to a casing in which the jaws and a plunger are mounted.

The invention is illustrated in the accomwherein Fig. 1 is a perspective view showing the tool in use;

Fig. 2 is a view showing the tool partially in longitudinal section and partially a tool by means min elevation;

Fig. 3 is 'a transverse sectional view taken through the casing'on the line 3-3 of Fig.

2; and 0 Fig. 4 is a transverse sectional view through the casing on the line 4-4 of Fig. 2.

The casing 1 through which the plunger 2 passes is cylindrical in shape and at'its upper end is provided with a head 3 having an opening 4 formed` centrally therein to receive the plunger. The Casin is carried by a fhandle 5 which is prefera ly formed from a metal tube split longitudinally from its forward end and flattened to provide spaced parallel walls 6 joined along their upper edges. The forward end portions of the walls 6 are severed to provide longitudinall extending tongue portions bent and imite at their ends to form `a sleeve 7 which fits snugly about the casing 1 and may be brazed, soldered or otherwise firmly secured thereto. Within the casing the plunger is formed with opposed side recesses 8 having arcuate upper and lower ends, as shown in Fig. 2, and adapted to receive the substan- Vso that the spring cannot readily move out tially circular end portions of the forks A9 provided at the forward end of the actuating handle or lever 10. This handle ,or lever 10 extends longitudinally of the handle 5' between the spaced. walls 6 thereof and is pivot-ally mounted through the medium of a pin 11. A spring 12 is carried by the handle 5 between its walls 6 and extends longitudinally thereof. The free rear end portion of the spring is folded back 'upon itself, as shown at 13 in Fig. 2, and this folded end portion of the spring' rests in a longitudinally extending groove 14 formed along the inner edge face of 'the lever 10 of proper engagement with the ver. The

lever l0 will, therefore, be normally held in the position shown in Fig. 2but may be swung against the action of the spring to the position shown in Fig. 1 when the handles are gripped and the plunger moved longitudinally in an operative direction and exert pressure against the transparent covering carried by the typewriter key 15.

In order to grip the ring or collar 16 which holds the transparent covering disk 17 in place, there has been provided jaws 18 which are formed of resilient metal. These jaws are preferably rectangular in cross section and have their upper end portions fitted into grooves or seats 19 formed in the peripheral edge face of a collar 20 in spaced relation to each other circumferentially of the collar. The extreme upper end portions of the jaws are bent to form side arms 21 which fit into extensions of the seats 19 and these side arms are engaged by a disk 22 held firmly upon the disk by outward swagin of a neck 23 projecting upwardly from ghe disk. .The jaws project 95 through .openin s 24 formed in a cap or closure 25 for t e lower endof the casing, and from an inspection of Fig. 2 it will be readily seen that when the cap is screwed upon the casing the collar and jaws will 100 be firmly but releasably held in place. If desired, the cap 25 may be omitted and a set screw passed through the casing radially thereofand screwed into a threaded socket formed in the collar to securely but re- 105 movably' retain the collar -in place. The jaws extend in dii-'erging relation to each other from the casing but have their Afree end poi-tions converging and terminating in hooks 26 adapted to engage beneath the re- 110 key. A'disk 27, which may be formed ofv taining ring or collar 16 of the typewriter any suitable material and is provided with openingsto receive the jaws, is slidablymounted thereon and when moved-towards the free endsv of the"aws will serve to move the jaws Itowards eacli other and retain them in gripping engagement with the ring 16.

When the tool is in use, the plunger-1s engaged with the upper face of the transparent disk 17 and the hooked ends of the 4 jaws disposed beneath the ring 16. The disk 27 is then slid downwardly to contract theV jaws and pressure applied to the vhandles 5 and to impart downward movement to the plunger and upward movement to the cas? mg. This pressure will cause the jaws to draw the ring or collar 16 upwardly while the plunger holds the key and covering disk stationary and the rin will be very easily removed. A padded t1 28 is provided at the lower end of the p unger so that there will be no danger of the transparent disk which is 'usually formed of lass being broken. While it is stated that t e tool is to be used to remove a collar from a typewriter key, it will be understood that, if made of a proper s ize, it could be used to remove the hands of a clock to-draw a collar or fly wheel from a shatt or for any other similar purpose.

Having thus described the invention, we
